    Summary: We study the geometry of light-like submanifolds \((M, g, S(TM), S(TM^\perp))\) of a semi-Riemannian manifold \((\widetilde{M}, \tilde{g})\) of quasiconstant curvature subject to the following conditions: (1) the curvature vector field \(\zeta\) of \(\widetilde{M}\) is tangent to \(M\), (2) the screen distribution \(S(TM)\) of \(M\) is totally geodesic in \(M\), and (3) the coscreen distribution \(S(TM^\perp)\) of \(M\) is a conformal Killing distribution.
